On the second-order cyclic statistics of signals in the presence of receiver impairments
(IEEE-INST Electrical Electronics Engineers Inc, 2011-12)
Cyclostationary characteristics of communication signals can be exploited for performing various signal processing tasks. Receiver impairments that affect the cyclic statistics of signals may lead to a degradation in the ...
Model selection in omnivariate decision trees using Structural Risk Minimization
(Elsevier Science Inc, 2011-12-01)
As opposed to trees that use a single type of decision node, an omnivariate decision tree contains nodes of different types. We propose to use Structural Risk Minimization (SRM) to choose between node types in omnivariate ...
Monolithic CMUT-on-CMOS integration for intravascular ultrasound applications
(IEEE-INST Electrical Electronics Engineers Inc, 2011-12)
One of the most important promises of capacitive micromachined ultrasonic transducer (CMUT) technology is integration with electronics. This approach is required to minimize the parasitic capacitances in the receive mode, ...
Failure analysis and warranty modeling of used cars
(Pergamon-Elsevier Science Ltd, 2011-09)
Reliability is an important aspect of product perception and manufacturers are compelled to take corrective actions on the items failing within the warranty period. Automotive manufacturers are being exposed to significant ...
Reliability evaluation of healthcare services by assessing the technical efficiency
(Routledge Journals, Taylor & Francis Ltd, 2011)
Classical reliability analysis techniques of manufacturing and defence industries are not a perfect fit for the assessment of the reliability of services. This is partly due to the lack of proper and valid reliability ...
Decoder side true motion estimation for very low bitrate b-frame coding
(IEEE, 2011)
In H.264 standard, coding of motion vectors constitutes a significant portion of total bitrate especially at low bitrate regimes. This is because differential coding of motion vectors is inefficient when the bit budget is ...
Optimum power control for transmitter cooperation in OFDMA based wireless networks
(IEEE, 2011)
For a cooperative orthogonal frequency division multiple access (OFDMA) system with two transmitters (TXs), and full channel state information (CSI), we obtain the optimal power allocation (PA) policies which maximize the ...
An Analog beamformer for integrated high-frequency medical ultrasound imaging
(IEEE, 2011)
We designed and fabricated a dynamic receive beamforming integrated circuit (IC) in 0.35-mu m CMOS technology. This beamformer is suitable for integration with an ultrasound annular array for high-frequency (30-50 MHz) ...
A quasi-one-dimensional bubbly cavitating flow model and comparison with experiments
(European Turbomachinery Soc-Euroturbo, 2011)
A bubbly cavitating flow model is constructed for unsteady quasi-one-dimensional and two-dimensional nozzle flows. In each case, the system of model equations is reduced to evolution equations for the flow velocity and ...
Computational and asymptotic methods in aeroacoustics with applications
(Işık University Press, 2011)
In this article the computational and asymptotic methods used in aeroacoustics are reviewed. In particular, two different aeroacoustic applications are demonstrated.In the first problem we investigate the first and second ...
